Cuyamaca 100k Endurance Run is delaying the opening of registration by one month to 5/1/2020.  We hope that in the upcoming weeks, more information and guidance from our parks will allow us to more confidently accept your registrations and plan for the run on 10/3 this year.

We are also waiving qualification requirements in light of so many runs around the world being cancelled with little notice.

Thank you for your support and understanding.  If you have any questions please feel free to email me at cuyamaca100k@gmail.com.
